As an exercise, use incremental development to write a function called hypotenuse that returns the length of the hypotenuse of a right triangle given the lengths of the other two legs as arguments. Record each stage of the development process as you go. (Downey, 2015) After the final stage of development, print the output of hypotenuse(3, 4) and two other calls to hypotenuse with different arguments. Include all of the following in your Learning Journal: An explanation of each stage of development, including code and any test input and output. The output of hypotenuse(3,4). The output of two additional calls to hypotenuse with different arguments.
